ELI DRAKnbE 'rnoia` NEW roam` :BOOT-CRIMP.

Specicationof` Letters Patent No. 3,340, `datedl November 15, 18431 Toall 'whom t may concern j N l Be it known that I, ELI P. DRAKE, of thecity of Troy, in the count-y of Rensselaer and State of New York, haveinvented a new and useful Improvement in the Mode of Crimping Boots,called the` Power Crimp-Board; and I do hereby declare that thefollowing isa full, clear, and exact description of the construction andoperation of the same, reference beinghad to the annexed drawing, makinga part of this specification, in which- A, represents the front board;B, the foot piece; C, the back board; D, a movable block; E, E, E,pincers; F,\F, levers; G, a nut; I-I, a screw; I, a stationary postbetween levers; K, K, but-ts, or hinges; L, L, springs; N, N, N, N,posts; R, R, R, stationary castings.

A, the front board made ofwood, or other material, is constructed in theordinar form of a crimp board; B, the foot piece, attached to A, thefront board, by hinge K, is constructed of the like material, and inlength, extends to block D; C, the back board, attached to A, the frontboard,

j by hinge K, is constructed of the like material, and extends in lengthto block D; D

isa movable block, made of the like material, and is constructed in theform of a wedge,iof any size, suitable to the size of the machine; R, R,R, are stationary castings, of iron, brass, or any other suitablematerial, of any size corresponding to the size of the machine-thecastings fixed upon the foot piece B, and back board C, having ears orprojections upon the sides to which are fastened the pincers E, E, andears or projections on the upper surface to which are fastened theleversF, F, by pivot, hinge, or otherwise; and the casting upon block D,

having ears, or projections only on its sides to which are fastened thepincers, E, E; the

said castings beingfastened upon the foot` piece, back board, andmovable block, at any suitable pointfor convenient use; I, I, are centerposts, between levers F, F, rising from castings R, R, on foot piece B,and back board C; F, F, are levers, fastened to castings R, R, by pivot,or hinge or otherwise,*that part of each lever which falls betweencenter posts I, I, and pincers E, E, being ina-de in the form of awedge, and the rest in any form to suit the taste of the maker; E, E, E,are pincers fastened by a fagainst and shut `whereon the screw pivot orotherwise; tofcastings R,1;R,\R, and

`of a size and length corresponding to the 'size of@ the machine, thesurfaces thereof falling upon the foot piece, back board, and -movableblock being serrated orl dentated,

so as to clasp theleather more firmly;G is

,a movable nut upon screw I-I, made in the form of a` wedge, andlargeenough to rise pincers R, ont block D, is turned upward; I-I is ascrew, of-"iron, brass;V or `other suitable {materia-L- passing throughmovable nut G,

through stationary casting R, andwthrough block D;-jagainst,` or intofront board A;

N, N, N,- N, l are stationary posts; of iron, or other suitablematerial, upon piece B, back board C, and block D, move, and by means ofwhich their motions are made steady and regular; L, L, are springs, ofwire, or otherwise, by means of which, foot piece B, back board C, andblock D, are drawn back to their proper place after using.

The drawing accompanying this specification, and being a part thereof,presents a view of one side of the power crimp board, of which the otherside is an exact counter` part. j

The power crimp board is used in the following manner, viz: The leatherbeing lirst cut into the of a boot, and being in a suitable state forcrimping, is laid upon front board A, and the corners of the leatherplaced between the pincers E, and block D. Then the screw H, is turnedso as to raise the nut G, against the pincers, thereby clasping theleather firmly between the pincers E, and block D. The levers F, F,being then raised so as to open the pincers E, E, on foot piece B, andback board C, the leather is placed between pincers E, E, and foot pieceB, and back board C, and the levers are'then shut down and the leatheris firmly clasped. The screw H, being then turned, the block D, israised, which pressing against the footpiece B, and backboard 'C liftsthem upward, and outward and thereby stretches the leather in threedifferent direct-ions at one and the same time. Any wrinkles in theleather may be smoothed down in the usual way by a shoemakers hammer, orlong stick, and the crimping is done;

I donot claim the invention of a form for which foot proper form for thefront part a boot-crimp, as the form must in all cases be nearly thesame. But

I do claim- 1. The division of the crimp board into parts, as describedin the above specication.

2. I also claim that combination of the lever and pincers upon oot-pieceB, and back board C, by which the leather is clasped to the foot-pieceand back-board.

3. And here I claim the privilege of using this combination of the leverand pincers upon the block D, for the purpose of clasping the leather toblock D, if I should nd it convenient to do so, instead of using the nutG, and pincers E, as above described.

.4. I also claim the combination of the foot-piece B, back-board C,block D, screw I-I, nut Gr, and pincers E-by which combination, when thescrew I'I, is turned, block D, is raised against footpiece B, and backboard C, lifting them upwards and outwards and at the same time the nutG is raised against the pincers E, thereby clasping the leather firmlyto block D, the result of the whole combined movement being to `D, bythe lever and pincers, as in my second vclann above mentioned.

6. Wherever pincers are above named, I only claim them in combinationwith other parts of the machine.

In testimony whereof, I, the said ELI l?. DRAKE, hereto subscribe myname in the presence of th-e witnesses whose names are heretosubscribed, on this thirtieth day of October A. D. one thousand eighthundred and forty three.

ELI P. DRAKE.
